Which is the most suitable reagent for the following conversion ?

Options

  1. ATollen's reagent
  2. BBenzoyl peroxide
  3. CI ₂ and NaOH solution with subsequent acidification
  4. DSn and NaOH solution

Correct answer

C. I ₂ and NaOH solution with subsequent acidification

Step-by-step solution

In the given reaction - COCH ₃ group gets oxidised to - COOH without affecting the double bond. This could occur when we use I ₂ and NaOH solution with subsequent acidification. This reaction is known as iodoform reaction. The overall reaction is as follows
